> Found this issue when deploying on real clusters. If there are apps running when we enable
timeline v2 (with work preserving restart enabled), node managers will fail to start due to
missing app context data. We should probably assign some default names to these "left over"
apps. I believe it's suboptimal to let users clean up the whole cluster before enabling timeline
v2.
